p-Coumaric acid ? a monomer in the sporopollenin skeleton [PDF]
Planta, 1989 Sporopollenin obtained from wings of Pinus mugo (Turra) pollen was analysed by pyrolysis mass spectrometry. In the spectrum, mass peaks which are characteristic for p-coumaric acid were dominant. p-Coumaric acid was the main degradation compound when the wing material was treated by a gentle method using AII3, and also when the remaining residue of the

The Crystal Structure of p-Coumaric Acid [PDF]
Nippon kagaku zassi, 1967 p-クマル酸の固相皿合の可能性を検耐するために,その結晶構造をX線解析法によって研究した。この結晶は単斜晶系に嘱し,8=8.71±0.01,b=5.26±0.01,c=17.24±0.02Å,β=100.0±0.2° なる大きさの単位格子中に,4個の分子を含んでいる。空間群はP21/Cである。反射強度は.GuKa線を用いて,β 舳およびb軸のまわりで等角傾斜法によって撮影した積分Weissenberg写真から.目視法で測定した。構造は賦膠法によって解き,異方惟温度因子を用いたブロック対角近似の最小二乗法によって精密化した。最終のR因子は12.9%である。最終のパラメーターで計算したD合成から,カルボキシル基の水素以外の全水素原子を見つけだすことができた。この分子は,カルボキシル基同志の強い水素結合 ...
